"The Visitor" is the 75th episode of the American syndicated science fiction television series Star Trek: Deep Space Nine and the second episode of the fourth season. The episode was written by Michael Taylor and directed by David Livingston. It originally aired on October 9, 1995.

Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy. In this episode, an accident leaves Captain Benjamin Sisko frozen in time, leaving Jake with a lifelong obsession of rescuing his father while having his resolve tested when they briefly reunite every few decades.

The episode was nominated for a Hugo Award for Best Dramatic Presentation in 1996, but lost to Babylon 5's "The Coming of Shadows". It consistently ranks in polls as one of the most popular episodes of the entire series, often vying for first place with "In the Pale Moonlight" and "Trials and Tribble-ations", with one critic writing that the episode "sums up everything that made DS9 so unforgettable."

The episode is mostly set in the 25th century, starting in the year 2450. On a rainy night on Earth, the elderly Jake Sisko (Tony Todd) is visited by an aspiring novelist Melanie (Rachel Robinson), who is curious to learn why Jake gave up writing after publishing two successful books. Jake, knowing the time in his life is short, decides to tell her his story, revealed as flashbacks in the episode.
